2. Reason / A. Nature of Reason / 9. Limits of Reason
You can't reason someone out of an irrational opinion [Swift]
     Full Idea: Reasoning will never make a man correct an ill opinion, which by reasoning he never acquired.
     From: Jonathan Swift (Letters to a Young Clergyman [1720])
     A reaction: It would be hard to prove this, and someone full of irrational beliefs may have their rationality awakened by a sound argument. Nice remark, but too pessimistic.
2. Reason / B. Laws of Thought / 2. Sufficient Reason
Chrysippus said the uncaused is non-existent [Chrysippus, by Plutarch]
     Full Idea: Chrysippus said that the uncaused is altogether non-existent.
     From: report of Chrysippus (fragments/reports [c.240 BCE]) by Plutarch - 70: Stoic Self-contradictions 1045c
     A reaction: The difficulty is to see what empirical basis there can be for such a claim, or what argument of any kind other than an intuition. Induction is the obvious answer, but Hume teaches us scepticism about any claim that 'there can be no exceptions'.
